Question

Solve for x, which is a real number.

2x^2 + 5x = 8

Tried a bunch of different times, never produced a correct answer, help?

Answer 1

I hope you know the concept of quadratic equations, since you are gonna need it for this question.

Answer 2

I do, but none of them have yielded a correct answer. Just need some clarification on where I;ve gone wrong, perhaps.

Answer 3

What you will do in this is that, you'd subtract 8 from both sides and then solve the quadratic equation.

Answer 4

Oh, now I see it. Had a wrong negative, thank you.

Answer 5

You're very welcome; my pleasure to help.
